Differing with most analysis model which the near field distributions are calculated by FDTD and then far field are obtained by using of propagation method  we obtain the fields in whole computational space by using of FDTD only. The advantages are that all the results are vector based and the computational time is saved greatly. In this paper  we present two methods to obtain wave amplitude  one is comparison method  and the other is integral method. Depending on wave amplitude in the whole computational space  one can conveniently obtain distributions of electric field intensity and calculate the time-average Poynting vector. We also present the formulation for calculating diffractive efficiency of DML based on time-average Poynting vector which denotes energy flow. As demonstration  a DML is analyzed by using of these algorithms. The time depended graphic results of FDTD show the process of wave propagation. The distribution of electric field intensity illustrates the focusing of the normal incident light. The focus pattern in the focal plane is also show. The diffractive efficiency of the DML is calculated by using of the energy flow method in this paper. The results show the high accuracy and efficiency of the model. 2009 SPIE.   furstyling on angle-split shell textures 会议论文  OAI收割 22nd International Conference on Computer Animation and Social Agents (CASA 2009), Amsterdam, NETHERLANDS, JUN 17-19, Sheng Bin; Sun Hanqiu; Yang Gang; Wu Enhua   |  收藏  |  浏览/下载：25/0  |  提交时间：2011/03/20 furstyling  angle-split shell textures  vector fields  interactive modeling   Correlation between solar flare productivity and photospheric vector magnetic fields 期刊论文  OAI收割 ADVANCES IN SPACE RESEARCH, 2008, 卷号: 42, 期号: 9, 页码: 1475-1479 作者:  Cui, Yanmei;  Wang, Huaning 收藏  |  浏览/下载：15/0  |  提交时间：2017/03/21 Solar flare productivity  Vector magnetic fields  Magnetic measures   Flows associated to adapted vector fields on the Wiener space 期刊论文  OAI收割 JOURNAL OF FUNCTIONAL ANALYSIS, 2007, 卷号: 253, 期号: 2, 页码: 647-674 作者:  Gong, Fuzhou;  Zhang, Jingxiao   |  收藏  |  浏览/下载：17/0  |  提交时间：2018/07/30 flow  adapted vector fields  the modified Picard's iteration method  the Wiener space
